anyone knows how much is it now and where to get it? still $980+? o.o
 

bought it at 940 sgd using credit card. but if you pay cash, its 920 sgd...seller is Alan Photo
 

by the way, since i bought it and paired it with my D7100, My dying interest in camera was cured!...its sharp sharp sharp!
 

thanks for the info man no problem. will pay by cash without a doubt! :)
 

anyone used this lense together with af assist lamp on a nikon flash? how accurate is it?

hmm well if a grey set is one that is without local warranty then I guess he's selling local sets now. it's with 2 years local sigma warranty. and if you register online you get six more months. so I guess it isn't a grey set :)

if it was then.... it's a super sharp grey set haha :)
 

I have not used flash with this lens so I can't comment. No much experience with using flash anyway. I took these shot in a restaurant without flash.

Haha yeah man when I saw the quoted price I thought it was too good to be true but it is!
He mentioned I took the last set available with him so.....I guess I was lucky too :)
Yeah would most probably be getting from alvinzzzz if there are any lenses I need.

but with the sigma 18-35.....hmm. doubt so. hahaha.
 

I've read quite a lot of reviews for this lens and a small number of them mentioned that there are times when the focus is totally off. Source:http://www.dpreview.com/lensreviews/sigma-18-35-1-8/5

also, i've read reviews that said the focus will hunt a little under low light conditions and/or have front/back focusing issues.

does anyone have focusing issues with this lens? i'm seriously considering this lens for my next purchase.
 

So far I have no issues with the Nikon mount of this lens. Maybe I got a good copy or Sigma calibrated for me when it updated a new firmware for this lens for the D5300 which initially cannot auto focus in Live View mode.

Hi, was a efs17-55, tamron 17-50 non-vc, sigma 17-50 OS user,
Now a 18-35 user, no complain so far, but do note the smallest aperture is f16 & no IS

If I buy it now, would the lens come with the latest firmware? Cuz my camera body is d5300 and it would suck if I have to spend another 80 bucks just to buy the USB dock. Does sigma charge you for updating the firmware? How long does it take to send the lens for firmware update/calibration?

I think Sigma has rectified the problem of auto focus of all new 18-35mm lenses for Nikon d5300. Lenses have sticker"Compatible With D5300" They will also update new firmware for free. Don't have to buy the USB dock.

I've just bought this lens but I think I have backfocusing issue at 18-20mm.

I took some sample test shots and my focus is aimed at the spot where the ruler touches the iPhone box.

35mm - Focus seems accurate

28mm - Seems accurate

24mm - Still accurate

20mm - Backfocus; Focus seems to be around the 7.5 inch mark on the ruler

18mm - Looks like it's the same as 20mm; Focus seems to be around the 7.5 inch mark on the ruler

Any tips when going to the service center?

I saw from another thread that
- must call them up first and make appointment
- bring my camera along
- bring the lens cap
- bring warranty card

Any other things that I should know?
 

I only send in my lens only as it cannot auto focus in Live View mode in the D5300 when the camera was first released. I send it just before Chinese New Year and it took one week because of the holidays. Maybe you can call them for more details that you want to know.
